Both things can be true. The chemistry soured and KD made it worse.
It’s okay to admit you’re wrong every once in a while. I admitted it about the KD trade being a disaster.
But saying the chemistry was “great” and our ability to hold leads, yada yada in the obvious face of one the most disastrous playoff collapses ever punctuated by the absolute worst Game 7 performance ever to a huge underdog in in second round run and the ongoing Ayton/Crowder issues that continued is just a joke.
Also, if Booker can be so easily swayed by someone like KD, whatever culture there was before KD must have been on the thinnest of ice. You didn’t see that with GS. They got KD and then the only reason they ever lost was because of injuries. Why? Because their leaders are actually LEADERS, not the checked out little follower that your golden boy is.
